City Island is downtown Harrisburg's major city park.  It is home to the Harrisburg Senators minor league baseball team, as well as the minor league soccer team.  City Island is accessible from downtown via the Walnut Street pedestrian bridge, or by car via Market street.  Besides hosting the two minor league teams, City Island also has batting cages, an arcade, miniature golf, Susquehanna Outfitters to rent kayaks, canoes and bikes, and river access.  It is also a local running and bike path as the loop around the northern part of the island is almost a mile long.  There are a variety of food and souvenir vendors open during the baseball games.  All other facilities are open seasonally.  Over all this is a great place to relax with family, dogs or alone if you have some time, and the kayak trips are a great alternate way to see the area.
